Description:Protect your identity and credit from unwanted card readers with this aluminium mesh screen sleeve. Many new credit cards have radio frequency ID chips in them which can be accessed by a card reader, which is normally in a retail store. Pass your card in front of the reader instead of scanning making purchases more convenient, but a scanner in the wrong hands can read your card from as far away as 70 feet. Our RFID protector sleeve stops scanners and protects you.
